The problem was the beep length like you said. It was set to 1 but when you go to the ide and look under my devices and click on the keypad under preferences the value showed 0. So even though it was 1 in the app it was showing 0 under the device. After I did an edit to 1 it know works.
I do have another question.
I have 2 keypads with them both selected but only one will chime.
Also when I open a door it takes a good 3 to 5 seconds before you get a chime. Is this normal?
